t all ai -Lamam emm; H Be it known thatI, ANGELO DAsonivzo,

a subject of the King of Italy,v residing at Denver, inthe county of Denver and State of Colorado, have invented certain new and useful Improvements in Methods forRepense of installation and maintenance of which is very considerable.

In accordance with the method of this invention, the gas is collected from various parts of the mine,is compressed into. a smaller volume, into a pressure flask, for exam-pie, and the flasks are shipped'out of the mine from time to time; The dust'collected may be put into bags or other containers, and theseshipped out of themine.

The preferred formzof apparatus for car,

rying out the method comprises essentially a portable unit, mounted on a wheeled truck that can readily be run to any desired. part of themine. On' the truck there is mounted suction producing means,'withwhich are connected two or more flexiblesuction pipes,

' one for reaching to the roof of the mine, for

collecting the gas which usually collects there, and the other for reaching to the floor of the mine for collecting dust.

The collected gas and dust are preferably kept separate. The gas is delivered to a compressor, Wl'llCll compresses 1t into smaller volume, into a pressure flask. These flasks may be shipped out of the mine from time to time. The dust may be bagged, orotherwise disposed of.

The suction means preferably comprises two fans mounted in separate casings on a commorr shaft. One motor is preferably used to drive both fans and the compressor.

Further details of theinvention and ad-' ditional features of construction and operation will be apparent from the accompany ing drawing, illustrating one possible embodlment of apparatus for carrying out the iiiventi'on. These drawings are" more 101- less dlagranimat'lc. 3 In these -draw1-ngs,

Fig; 2 is a plan View of the. same. i Referring more in'detail'to these drawings in l which similar reference characters iiicli catecsim'ilar parts, the roof an'd floor of the f' Fig. 1 is aside view of the; apparatus, and l m'ine are indicated at R andjF respectively.

vided with wheels 2, which may beflanged for: running on -the usual 'minetrack's 3, or 'WhlCll may be wheelsof a suitable type for running on thelfloor of thejmineVMount ed on the truck 1s an electrlc motor 4 which,

drives a shaft 6 1n0unted"'in* bearings? Fixed on the shaft 6 is a pair of suction fans 8 and 9 mounted in separate casings 11 and12 respectively. A partition 13 is pcsitioned between, the fans, so that the materials sucked in bythem are kept separated. A flexible suction pipe 14, provided with Theapparatus comprises a truck 1- pro- ,theusual. nozzle 15 is connected to one fan cas1ng,here shown as casing 11. This suc .t1on' plpemay be used for collecting gas from theroof of the mine, where it usually collects, although of course it is made long enough 'to'reach the floor ofthe mine in case the gas'should collect there. The pipe 14 is preferably manually operated.

, The gas collected by pipe 14 is led into casing 11 and thence delivered to a pipe 16 provided with avalve 17 and a branch pipe 18 having a'valve 19. The pipe 18 delivers to gas compressor 21, which compresses it to a' high-pressure and delivers it, through a pipe 22, to any one of a plurality of pressure flasks 23, provided with the usual valves 24.

motor 4 by'a pulley Wheel 26 onshaft 6, which drives a belt 27 and pulley wheel 28 on the shaft ofthecompressor.

A second flexible suction pipe 31 having a nozzle 32 is connected to the other fan cas- 7 ing, here casing 12. The pipe 31 is long enough to reach to the floor or roof as de- The'compressor 21 may be driven from loo sired, but is primarily used for collecting dust from the floor of the mine. The collected dust is discharged into a pipe 33 and pipe 34, having a valve 35, and a side outlet pipe 36, provided with a valve 37. Pipei36 delivers the dust into a dust collecting 38; the dust filled bags may be periodlcaily shipped out'of the mine. The dust couldbe oitenas, needed.

otherwise disposed of through opening valve 35. 'The pipe 31 is preferably manually operated. V p i v The truck of course carriesa number of flasks and bags for the 'gas and dust, so when one is filled, another may be substituted.

I It will therefore be seen that, this apparatus Will collect gas and dust from amine,

and will put the gasand dust in separate;

containers Which may be periodically shipped out ozfi the mine The. gas anddust may thus be removed from, the mine byrunning the truck 1 through themine as The expense of installation and maintenance 01? gas pipes and pas-' sages is. entirely eliminated.

It should bev understood tha-t'thedrawing is; illustrative of one way of carrying out the inazention, and that the; invention isnot to, be limited to the/specific, details; here shown, but maybe carried out-in other'ways. Havingthus described my invention, What Icla-im asne-w and desire: to. secure by Letters Patent? 7 1. method for removing gas-and dgust from, a 1111119,; without the use of fixedv pipes dust from'the mine With a plurality of suction nozzle devices carried by the can, storing the collected gas and d'ust inappropriate containers on the, car, and periodically shipping the containers out of the mine.-

3. The method of removing dust and gas from mines Without the use of a fixedpiping system, compris ng running a car through the mine, simuiltaneously collecting gas and dust fromv the, mine, with a pair oaisuction nozzle devices carriedby thecan-compress ing the gas, storing the collected gas and dust in containers carried by the car", and

periodically ship-ping the containers out of the mine. a e v In.- testimony whereof, I aflix, my signature.
